The crusher is a machine that crushes large-sized solid raw materials to the required size. The crusher consists of coarse crushing, fine crushing, wind conveying and other devices, in the form of high-speed impact to achieve the purpose of the crusher. The use of wind power to powder once, eliminating the traditional screening process. Mainly used in mining, building materials and other industries.
According to the size of the crushed material or crushed material, the crusher can be divided into coarse crusher, medium crusher, fine mill, and ultra-fine mill. There are four kinds of external forces applied to the solid in the crushing process: rolling, shearing, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and large materials; Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials; Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials; Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles grinding.

Mill product application technology principle:
When the mill is in production and operation, the motor drives the spindle and the turbine to rotate at high speed (the maximum speed can reach 700r/min). The turbine and the grinding block on the screen ring form a crushing and grinding pair, which has a compact structure. When the material enters the machine cavity through the hopper, the material entering the machine cavity is tightly rubbed and strongly impacted to the inner edge of the turbine blade in the rotating air flow, and is ground again in the gap between the blade and the grinding block. At the same time as crushing and grinding the material, the turbine draws in a large amount of air, which plays a role in cooling the machine, grinding the material and transferring the fine material: the fineness of the material crushing depends on the nature of the material and the size of the screen, as well as the amount of material and air passing through. The bearing part of the mill (crusher) is equipped with a special maze seal, which can effectively prevent dust from entering the bearing chamber, thus extending the service life of the bearing. The door is equipped with two O-shaped rubber seals, no dust leakage and pollution of the operating environment.
